BOTTLE-TOP.

Specification of Letters Patent.

Patented Mar. 30, 1915.

Application filed February 2, 1914. Serial No. 816,026.

To all whom it may concern Be it known that I, OSCAR ROELKE, a citizenof the United States, residing in the city of St. Louis and State ofMissouri, have invented certain new and useful Improvements inBottle-Tops; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements in bottle tops and moreparticularly to those which are removably engaged with the necks of beerbottles or the like.

The object of the invention is to provide a bottle top of this characterwhich may be very simply and cheaply constructed and which will form aneffective closure for the top of a bottle when in position or mayreadily be removed by hand.

With the above and minor objects in view, the invention resides indetails of construction herein described and claimed and shown in thedrawings wherein:

Figure l is a side elevation of a bottle showing my improved top appliedthereto; F i g. 2 is a vertical section through the neck of a bottle andthe top thereon; Fig. 3 is a horizontal section on the line 33 of Fig.2; Fig. 4 is a similar view of a cap alone when removed from the bottle;and Fig. 5 is a plan view of the resilient retaining element of the top.

In the accompanying drawings, the numeral l designates a-bottle ofordinary construction provided with the usual external bead 2 around theupper end of its neck. The bottle forms no part of the present inventionbut closely coacts therewith.

Referring now, more particularly to details, my improved bottle topcomprises an inverted cup shaped, packing receiving socket 3 thedepending wall 4: of which is extended laterally as at 5, bentsubstantially upon itself as at 6, and is then extended in wardly toform an annular flange 7.

A single piece of resilient wire 8 is bent at suitable points throughoutits length as at 9 to form a polygonal retaining element. The bends orcorners 9 of this element are inserted within the space between theportions 5 and 7, which form a substantially U-shaped bead. When in thisposition, it will be seen that the individual resilient arms 10 of saidmember are disposed in position to snap over the head 2 on the bottle 1,when the top is applied. I preferably provide a packing disk 11 looselyseated within the socket 3 of the top, said packing disk beingcompressed when the resilient spring arms 10 engage the taperedunderside of the bead 2.

By reference to the drawings, it will be seen that the resilient arms10, when in their proper position, are so disposed in regard to thepacking disk 11, that they prevent said packing disk from becomingdisengaged from the top when said top is removed from the bottle. Ihis Iconsider a very important feature of my invention.

From the above described construction of parts, it will be seen that Ihave produced a very simple, strong and efficient bottle top which mayreadily be engaged with or disengaged from the neck of a bottle by hand,without the use of any instruments whatever.

What I claim as my invention is 1. A device of the character describedcomprising; a cap formed of a single piece of sheet metal and having apacking receiving socket and an annular inturned flange, a packing diskseated within said socket, and spring metal arms underlying said packingdisk and having their ends seated above said flange.

2. A device of the character described comprising; a cap formed of asingle piece of sheet metal and having a packing receiving socket and anannular inturned flange, a packing disk loosely seated within saidsocket, and a resilient polygonal retaining frame underlying said diskand having its corners resting on said flange.

3. A device of the character described comprising; a cap formed of asingle piece of sheet metal and having a packing receiv ing socket andan annular bead substantially U-shaped in cross section, a packing diskseated loosely within said socket, and a resilient rectangular frameunderlying said disk and having its corners seated within said U-shapedbead.

4:. A device of the class described comprising a cap member, the loweredges of the side flanges of which are bent outwardly and thenceinwardly to provide a channelshaped head, a packing disk arranged insaid cap member, and a substantially rectangular clip formed of a singlestrand of Wire and arranged in the cap member to In testimony whereof Ihave hereunto set permit the corners thereof to be received my hand inpresence of two subscribing Witin the channel-shaped bead, said clip re;nesses. taining the packing disk in place When the i cap member is indisuse and adapted for en: gagernent with the bead of a bottle neck inthe application of the cep theretg OSCAR ROELKE.
